Add conversion from clock to postion and trace in a few locations

Summary:
# Context

We are introducing EdenFS notifications to support scalable and ergonomic file system notifications for EdenFS mounts.

# This Diff

* For "interoperability" we will need to convert between a Watchman clock and an EdenFS position. This diff adds clock->position and uses to do some simple tracing.

# Next Steps

* Complete the remaining FileWatcher methods
